4 Claims. (01. 139-192) This invention relates to an improved type of loom reed of the pitch band type and is a divisionalapplication taken from our co-pending application for patent, Serial No. 122,896, filed 5. January 29, 1937, Pat. No. 2,149,204.01" February The primary object of this invention is to provide a loom reed so that the finished rib will gauge correctly as to diameter at all points thereon. Heretofore, in the manufacture of cotton reeds of the pitch band type, it has not been possible to get an accurate gauge of the ribs for the entire 1ength.- This irregularity of the diameter is caused partially from the half round wood strips which are used on each side of the splits and clampedv therearound by a pitched twine; These wood strips are subject to a varied amount of shrinkage, since they do not have a uniform degree of hardness. Also the tension 20 on the pitched twine will grow greater as the diameter of the spool from which it is drawn grows smaller, during the formation of the reed, resulting in a tighter winding of the pitched yarn as the spool becomes empty. All of this variation in the gauge of the ribs of the reeds'causes much trouble in cotton weaving. For example, a loom may be alinedto take a certain reed, and

upon turning this reed end for end, or turning the reed upside down, the inaccuracy of the rib cause the ribs are not accurate and thus are not properly centered. Should the loom not be aligned, every time the reed is installed, the 100m will not operate smoothly and the wear on the shuttle will be excessive.

It is a further object of this invention to provide a loom reed having the rib thereof encased in a metallic sheet or band of uniform diameter,

this band being adhesively secured around the loom reed of the pitch band type showing ametallic casing enclosing a portion of the ribs and broken away from other portions thereof;

Figure 2 is a sectional view through one of the ribs and taken along the line 2--2 in Figure 1;

Figure 3 is a sectional plan view taken along the line 33 in Figure 1;

will necessitate the realigning of the loom, be-

Referring more specifically to the drawing, the numeral l0 denotes a suitable loom reed made in accordance with the invention. This reed has end bars II. and splits l2, the ends of which are clamped between semi-circular, or half round members it. The splits are spaced apart from each other by means of a pitched cord i5. which is spirally wound around both of the members Hi during the construction of; the reed. .Additional metallic strips such as indicated by, the reference character iii are provided to re enforce the half-round members, I l. These metallic members I6 are likewise-bound in the half-round members by means of the spiralled I pitched cord 15. After the cord l5 has been wound around both of the half round members, a suitable cuff I8 is secured on each endthereof by means of suitablenails '19. This cuff also serves to hold the end bars II in position.

With the reed formed to thispoint, a suitable metallic band is formed over each rib so that the finished rib will be symmetrical at all points about the vertical center line of the splits. This band has a suitable adhesive ,2l applied to one side thereof, so that the projecting ends of splits l2 will be properly secured to the metallic band 20.

By providing the adhesive material'Z'l, which is usually of pitch, tar, or some other suitable adhesive substance, the vacant spaces between the ends of the projecting splits are properly filled. Also the pitch 2| on the interior surface of, the metallic band 2!] mixes with the pitch on the exterior of the. spiralled cord I5. It is thus seen that the splits are securely anchored between the half round members, thus eliminating any necessity of bending theprojecting ends to secure them in position. i It will be noted by observing Figure 4 that each endof the-metallic casing 20 is crimped as at 22, so that the ends of ribs will have a neat ap pearance. The crimped end also serves as an additional means for securing the metallic band properly upon the half round members. Figure 5 is an isometric view of a portion of a comb 25 having its rib covered identically in the same manner as the ribs of the loom reed III are covered. This comb has end bars H and splits l2 which are clampedbetween half-round wood members [4 and which are spaced apart from each other'byspiraled cord 15' substantially as in the preceding case. This rib' also has metallic bars I6, cufis I8 and nails IS. A cover is folded around the rib and crimped over the ends thereof as at 22 thereby providing a comb whose rib will gauge correctly, as to diameter at all points.

In the drawing and specification there has been set forth a preferred embodiment of the invention and although specific terms are employed they are used in a generic and descriptive sense only and not for the purposes of limitation, the scope of the invention being set forth in the appended claims.

We claim:

1. A loom reed, comb and the like formed from splits held in spaced relation to each other by a half-round wooden member on each .Side of the splits near each end thereof, and having a pitched cord wound spirally around the halfround members and passing between the splits to space the same from each other, a metallic covering for the half-round members completely encasing the half-round members and the outer ends of the splits, the ends of the metallic covering being crimped inwardly over and against the ends of the half-round members.

2. A loom reed, comb and the like formed from splits held in spaced relation to each other by a half-round wooden member on each side of the splits near each end thereof, and having a pitched cord wound spirally around the halfround members and passing between the splits to space the same from each other, a metallic covering for the'half-round members completely encasing the half-round members and the outer ends of the splits, the ends of the metallic covering being crimped inwardly over and against the ends of the half-round members, and an adhesive disposed between the ends of the splits and adheringto the interior surface of the metallic covering. I

3. A cotton loom reed, comb and the like having a rib formed from a pair of half-round members engaging opposed edges of the splits forming a part of the reed, comb and the like, a unitary metallic covering for the rib completely covering the half round members and the outer ends of the splits and having its edges in close proximity to an intermediate portion of the splits, the ends of the covering being restricted by having their edges crimped inwardly against the ends of the rib to securely position the coverof the rib to securely position the covering of the rib, and-an adhesive disposed between the ends of the splits and, the covering.
